Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25554, here are decompositions:

  • 13 + 25541 = 25554
  • 17 + 25537 = 25554
  • 31 + 25523 = 25554
  • 83 + 25471 = 25554
  • 97 + 25457 = 25554
  • 101 + 25453 = 25554
  • 107 + 25447 = 25554
  • 131 + 25423 = 25554

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25554 first appears in π at position 36,629 of the decimal expansion (the 36,629ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
